The album includes "Empty Garden (Hey Hey Johnny)", a tribute to John Lennon (who had also signed to Geffen for the release of Double Fantasy, which is now owned by EMI). This is one of the first few LPs that showcases John singing in a deeper voice, as can be heard in songs such as "Blue Eyes", "Princess", "Ball and Chain" and "Spiteful Child". "Legal Boys" was written by John and Tim Rice, who later wrote lyrics for The Lion King and The Road to El Dorado. This is the last studio album in which James Newton-Howard played keyboards (he played keyboards again on the soundtrack of Gnomeo & Juliet less than 30 years later). In a 2010 Sirius radio special, John's lyricist, Bernie Taupin talking about Jump Up!, said it was "one of our worst albums". He added, "It's a terrible, awful, disposable album, but it had 'Empty Garden' on it, so it's worth it for that one song." In the United States, it was certified gold by the RIAA in November 1982. The album cover shows John's lifelong friend Vance Buck. After 1982, only "Empty Garden" and "Blue Eyes" have been performed regularly.
